Cross cultural adaptation and psychometric properties of the Arabic version of the Life Satisfaction Questionnaire (LISAT-9) in patients with chronic spinal cord injury.

PURPOSE: This study aimed to translate and culturally adapt the original English version of the life satisfaction questionnaire into Arabic (LISAT-9-Ar) and examine its psychometric properties among patients with spinal cord injury (SCI).

MATERIALS AND

METHODS

The translation and culturally adaptation into Arabic followed the published guidelines. The mental health subscale (MHI-5) of the 36-item short form health survey (SF-36), and the satisfaction with life scale (SWLS) were used to examine convergent validity. USING Spearman's correlation coefficient (rho). Reliability was tested after two weeks using intra-class correlation coefficient (ICC) and the internal consistency (Cronbach's α).

RESULTS

A total of 150 participants were recruited to test the convergent validity of the LISAT-9. LISAT-9-Ar showed a positive strong correlation with SWLS (rho = 0.81) and moderate correlations with the MHI-5 (rho = 0.66). Sixty participants were recruited to test reliability, the test-retest reliability was excellent (ICC = 0.94, 95% CI = 0.912-0.958 and Cronbach's α = 0.94). The SEM of the total score was 0.27 with an MCD 95 of 0.75 (18%) with no floor or ceiling effect.

CONCLUSION

The LISAT-9-Ar shows excellent psychometric properties supporting its usefulness for research and clinical purposes.
